ABSTRACT As we all know, pipeline provides a lot of convenience for mass and message transfer in industry, agriculture and daily life。 However, the pipeline transportation impacts on the production and living seriously as a result of the pipeline corrosion, aging, leak, siltation clogging。 In order to complete pipeline detection, fault diagnosis, repair more economically, Special pipe robot has become an extremely effective and feasible engineering solutions。

In this paper, the intelligent inspection robot (mechanical structure part) of the small pipe with the diameter of 160~250mm is studied。 The design of the pipeline robot load more than 200N, moving speed is greater than 100m/min, has solved the problem of traditional pipeline robot traction power shortage, poor load capacity。

Based on the operational principle of micro-pipe robot existing at home and abroad and the analysis of crucial technique, this paper puts forward such a designing idea about chain multiple-unit screw initiatively type pipeline robot。 Analyzed and compared the advantages and disadvantages of many ways of Transmission mode, driving mode and running mode on the basis of function requirements of pipe robots, the general scheme of the mechanical design of the pipeline robot is designed。 Furthermore, according to the design scheme and design requirements, mechanical design for waking mechanism, body mechanism and tensioning mechanism of pipe robot are calculated and checked。 Then, the performance evalution of pipe robot is completed, whih is based on the analytic result of load capacity, speed and climbing ability。 Finally, the robots is modeled, assembled, and made operation simulation and motion interference analysis。 It provide information for trial manufacture of physical prototype。

Keywords: pipe robot; chain multiple-unit; screw initiatively; motion simulation
